Common surgical complications in degenerative spinal surgery

World Journal of Orthopedics 2013年第2期4卷 62-66页

作者： Michael Papadakis Lianou Aggeliki elias C papadopoulos Federico P Girardi Resident in Orthopedic Surgery University of Athens School of Medicine 10676 Athens Greece Resident in Radiology St. Olga Hospital 10676 Athens Greece Spine Service School of Medicine University of Athens 10676 Athens Greece Attending Spine Service Hospital for Special Surgery New York NY 10021 United States

The rapid growth of spine degenerative surgery has led to unrelenting efforts to define and prevent possible complications, the incidence of which is probably higher than that reported and varies according to the region of the spine involved(cervical and thoracolumbar) and the severity of the surgery. Several issues are becoming progressively clearer, such as complication rates in primary versus revision spinal surgery, complications in the elderly, the contribution of minimally invasive surgery to the reduction of complication rate. In this paper the most common surgical complications in degenerative spinal surgery are outlined and discussed.

On Word Equations Originated from Discrete Dynamical Systems Related to Antisymmetric Cubic Maps with Some Applications

引用

Acta Mathematica Sinica,English Series 2018年第11期34卷 1663-1676页

作者： elias ABBOUD The Academic Arab Institute Faculty of EducationBeit Berl College

In this article, we solve some word equations originated from discrete dynamical systems related to antisymmetric cubic map. These equations emerge when we work with primitive and greatest words. In particular, we characterize all the cases for which （β1β1） = （β2β） where β1 and β2 are the greatest words in 〈〈β31〉〉 and 〈〈β32〉〉 of M（n）.

Real-time calculation of fragment velocity for cylindrical warheads

引用

Defence Technology（防务技术） 2019年第3期15卷 264-271页

作者： David Felix Ian Colwill elias Stipidis Institution of Engineering and Technology Stevenage England Member of British Computer Society London Institute of Electrical and Electronics Engineers London

To simulate explosion fragments, it is necessary to predict many variables such as fragment velocity, size distribution and projection angle. For active protection systems these predictions need to be made very quickly, before the weapon hits the target. Fast predictions also need to be made in real time simulations when the impact of many different computer models need to be assessed. The research presented in this paper focuses on creating a fast and accurate estimate of one of these variables - the initial fragment velocity. The Gurney equation was the first equation to calculate initial fragment velocity. This equation, sometimes with modifications, is still used today where finite element analysis or complex mathematical approaches are considered too computationally expensive. This paper enhances and improves Breech’s two-dimensional Gurney equation using available empirical data and the principals of conservation of momentum and energy. The results are computationally quick, providing improved accuracy for estimating initial fragment velocity. This will allow the developed model to be available for real-time simulation and fast computation, with improved accuracy when compared to existing approaches.

Effect of TiO_2 nanoparticles on hydrogen evolution reaction activity of Ni coatings

引用

International Journal of Minerals,Metallurgy and Materials 2018年第4期25卷 472-479页

作者： Revanna Kullaiah Liju elias Ampar Chitharanjan Hegde Electrochemistry Research Lab Department of Chemistry National Institute of Technology Karnataka

The electrocatalytic activity of electrodeposited Ni and Ni–TiO2 coatings with regard to the alkaline hydrogen evolution reaction（HER） was investigated. The Ni coatings were electrodeposited from an acid chloride bath at different current densities, and their HER activities were examined in a 1.0-mol·L^-1 KOH medium. The variations in the HER activity of the Ni coatings with changes in surface morphology and composition were examined via the electrochemical dissolution and incorporation of nanoparticles. Electrochemical analysis methods were used to monitor the HER activity of the test electrodes; this activity was confirmed via the quantification of gases that evolved during the analysis. The obtained results demonstrated that the Ni–TiO2 nanocomposite test electrode exhibited maximum activity toward the alkaline HER. The surface appearance, composition, and the phase structure of all developed coatings were analyzed using scanning electron microscopy（SEM）, energy dispersive spectroscopy（EDS）, and X-ray diffraction（XRD）, respectively. The improvement in the electrocatalytic activity of Ni–TiO2 nanocomposite coating toward HER was attributed to the variation in surface morphology and increased number of active sites.
